Avidemux Cannot Use That File As Audio Track -

Error Message: Avidemux cannot use that file as audio track
Software: Avidemux (commonly v2.7+ on Windows/Linux/macOS)
Context: User attempts to load an external audio file (MP3, AAC, WAV, etc.) as a replacement or additional audio track for a video.
Symptoms: Error appears immediately after selecting the audio file, preventing further processing.

| Cause | Explanation | |-------|-------------| | Unsupported audio codec | Avidemux natively supports AAC, MP3, PCM (WAV), AC3, and MP2. It struggles with Opus, Vorbis, FLAC, DTS, or lossless WMA. | | Wrong container format | Even if the audio codec is fine, the container (e.g., MKV, MP4, M4A, OGG) may confuse Avidemux’s demuxer. Raw .wav or .mp3 files work best. | | Variable Bitrate (VBR) MP3 | Avidemux’s MP3 parser (based on older libraries) often fails with VBR MP3 files, especially when seeking or appending. | | Multichannel or unusual sample rates | Files with 5.1/7.1 surround, 44.1kHz (ok), 48kHz (ok), but unusual rates like 22.05kHz or 96kHz may trigger the error. | | Corrupted or incomplete audio file | A truncated download or bad rip can break Avidemux’s strict parsing. | | File path issues | Less common on modern OSes, but spaces, Unicode characters, or network drives have been known to cause this error. | avidemux cannot use that file as audio track
